Gz’rylok is a compact, glossy-black kenku with close-laid feathers that catch faint blue-violet highlights when he turns beneath a lamp. He occupies less space than his travel chest, yet somehow makes a whole table feel like his office by arranging every object into precise rows. His ink-black eyes hold still on a speaker while his head makes tiny, abrupt counting tilts. A little brass abacus hangs from his belt; its thumb-worn center beads have been polished nearly smooth, and he touches them whenever someone gives him a number. He moves with careful, pigeonlike steps, then darts suddenly to correct a misplaced item. The unexpected detail is that he wears a small, carefully maintained knitted wool cap beneath his hood, its bright saffron tassel bobbing against his black plumage.

Soft-spoken and observant, Gz’rylok lets others fill silence while he studies what they do with it. He is patient with honest confusion but abruptly exacting with careless claims. In a calm mood he is wry and quietly generous; under pressure he becomes restless, repeats figures, and can treat a frightened person’s story as a problem to reconcile rather than a plea to hear.

Gz’rylok grew up around the loading yards of a dwarf-run caravan house, where he learned to recognize merchants by their boots, their pauses, and the sounds they made when they lied about a shipment. The caravan factor who first hired him, Durnik, valued his attention but taught him that a correct count mattered more than a charming explanation. Years later, during a night crossing of the Splitstone Ford, Gz’rylok noticed that the wagons’ wheel tallies did not match the axle inventory. He insisted they stop, saving the train from a sabotaged bridge approach, but his warning came too late to prevent the loss of a driver and several crates. That failure changed his habit of keeping figures in his head into an obsession with checking them aloud and twice over. Now he works as a junior factor for the caravan company locals call the Burdock Run, named for the weed that clings to every hem along the route. His mentor Durnik is proud of him but increasingly worried about his erratic late-night recalculations. Gz’rylok is also trying to help Tavi, a former teamster now blamed for the missing cargo, while quietly tracing who altered the original freight marks. His current accounts are short by a sum that is too exact to be an accident.
